AC Replacement
AC replacement and installation in Phoenix, sized for your house.
Central AC, heat pump and package unit installation for Phoenix homes. Every major brand, sized right, quoted in writing.
When your air conditioner is done, you need a new system that is sized right, installed right and priced in writing. RYZ Comfort replaces and installs central air conditioners, heat pumps, package units and ductless mini-splits across the Phoenix Valley, from Trane, Carrier, Lennox, Goodman, Rheem and every other major brand. We run a real load calculation on your home instead of matching the old tonnage, then show you good, better and best options side by side.
Every type of home cooling system
Most Phoenix homes cool with one of three systems. A split system has an outdoor condenser and an indoor air handler or furnace in the attic, garage or closet. A package unit puts everything in one cabinet on the roof or on a ground pad, which is common on Valley homes built in the 1980s and 1990s. A heat pump looks like an AC but also heats in winter, and it is the most common setup in Arizona.
We replace all three, like for like or as an upgrade. We also install dual fuel systems that pair a heat pump with a gas furnace, and ductless mini-splits for additions, garages and casitas.
Sized with a Manual J load calculation
The most common mistake in AC installation is copying the old tonnage. An oversized unit short cycles, leaves the house clammy and wears out early. An undersized one runs all afternoon in July and never catches up. We measure your home, windows, insulation and sun exposure and size the new system with a Manual J load calculation, the industry standard method.
Efficiency, SEER2 and the new refrigerants
New central air conditioners sold in Arizona must meet the federal Southwest efficiency standard, rated in SEER2. Higher SEER2 and variable-speed equipment cost more up front but cut cooling bills in a climate where the AC runs for most of the year. We show you the running cost difference so the choice is clear.
New systems now use the newer A2L refrigerants, R-454B or R-32, in place of R-410A. If your current system still runs on R-22, repairs are expensive because that refrigerant is no longer made, and replacement is usually the better value.
What a RYZ Comfort installation includes
Every job includes permits where required, removal and haul-away of the old equipment, a new pad or roof curb as needed, a refrigerant line flush or replacement, sealed connections at the plenum, and a full startup test with refrigerant charge, airflow and temperature split recorded on a startup report you keep. We register the equipment for its manufacturer warranty.

FAQ
AC Replacement questions
What AC brands do you install?
We install and service every major brand, including Trane, American Standard, Carrier, Bryant, Lennox, Goodman, Rheem, Ruud and York. We recommend equipment based on your home and budget, not on a single brand.
How much does AC replacement cost in Phoenix?
It depends on the size of the home, the type of system (split, package unit or heat pump), the efficiency level and how much of the ductwork and electrical needs work. We give you a free written quote with the equipment model numbers, warranty and total installed price, with no surprise add-ons.
What size AC do I need?
Square footage alone is not enough to size an AC in Arizona. Insulation, windows, ceiling height and sun exposure all matter. We size every new system with a Manual J load calculation.
Should I get a heat pump or an AC with a gas furnace?
In the Phoenix Valley a heat pump is usually the better choice because winters are mild and it heats very efficiently. If you already have gas and want backup heat for the coldest nights, a dual fuel system pairs a heat pump with a gas furnace.
Can you replace a rooftop package unit?
Yes. We replace package units on roofs and ground pads, including crane lifts when needed, and can switch a gas package unit to a heat pump package unit.
How long does an install take?
Most straight replacements are done in one day. Package units that need a crane, duct changes or ductless multi-zone installs can take one to two days.
Do you offer financing?
Yes. See the financing page for options, including low monthly payment plans.
Are there rebates?
SRP customers may qualify for SRP Cool Cash and TEP customers for Efficient Home rebates on qualifying equipment. APS equipment rebates ended January 1, 2026, and the federal 25C credit expired at the end of 2025. See our rebates page for the current picture.
Too hot to wait?
Fast service across the Valley, with same-day appointments on most days. Upfront pricing, no overtime fees.
